ITU-T H.752 (11/2015) i Recommendation ITU-T H.752 Multimedia content provisioning interface for IPTV services Summary Recommendation ITU-T H.752 describes the metadata elements that are necessary for multimedia content provisioning, such as content description, distribution conditi
10、ons and the usage log report. Compared to the high-level specification of metadata for Internet protocol television (IPTV) services defined in Recommendation ITU-T H.750, multimedia content provisioning interface for IPTV services focuses on the metadata elements to be used at the interface between
11、content providers and IPTV service providers. This Recommendation specifies the requirement for audio and video (AV) content metadata provisioning, AV content metadata elements and data structure, procedure of exchanges for content between the content providers and IPTV service providers.

ITU-T H.752 (11/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication
14、 technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World
15、Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In so
16、me areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recogniz
17、ed operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The word
18、s “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that t
19、he practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation
20、 development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are
21、therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.

ITU-T H.752 (11/2015) 1 Recommendation ITU-T H.752 Multimedia content provisioning interface for IPTV services 1 Scope This Recommendation identifies the metadata elements which are necessary for multimedia content provisioning. Two types of audio and vid
26、eo (AV) content metadata are content catalogue metadata and business metadata. Content catalogue metadata describes AV content description and the rights holder of the content. Business metadata describes basic business description and the usage log report. This Recommendation describes the messages
27、 and procedures of exchanges for content between content providers and service providers in the two communication modes (push mode and pull mode). ITU-T H.750 already identifies essential elements and attributes concerning content. This Recommendation focuses on the content metadata to be used at th
28、e interface between content providers and Internet protocol television (IPTV) service providers. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

This Recommendation identifies the requirements for AV content metada
43、ta provisioning and the metadata elements and attributes which could be provided by AV content providers. This Recommendation describes AV content metadata elements and attributes which could be transferred from content providers to IPTV service providers, and be integrated by the IPTV service in el
44、ectronic programme guide (EPG)/electronic content guide (ECG) for content discovery. It also describes the requirements for AV content usage log information of end-user and payment details transferred from an IPTV service provider to content provider. Two communication modes are specified between co
45、ntent providers and IPTV service providers for the delivery and management of content metadata and content: 1) A push mode in which the content providers take the initiative to declare their content to the IPTV service providers. 2) A pull mode in which the IPTV service providers, having a reference
46、 to particular content, request information about this content. 7 Requirements for AV content metadata provisioning The metadata schema for the contents to be transferred between the content provider and IPTV service provider is required to support: Req1: the intention of the metadata set (new, repl
47、ace, append). Req2: the identification of the content provider, source of the metadata set. Req3: the content description with elements such as content identification used by the content provider, title, description, keywords, genre. These elements should be taken from the elements already included
48、in metadata schemas specified for ECG/EPG delivery to end-user terminals. Req4: the business information of the content, such as price, charge type. Req5: the possibility to describe several contents in the same set. Req6: the possibility to group features common to all content such as AV attributes
49、. but also to allow individual contents to have different values for these common features. Req7: the possibility to give content location to allow the transfer of the content itself. Req8: the possibility to give content delivery information, such as distribution area and terminal device to be allowed to receive. Req9: the possibility to get the usage information of the content from the end user. 4 Rec. ITU-T H.752 (11/2015) Req10: the possibility to get the payment
